Rachel Leila Douglas-Home, 27th Baroness Dacre (née Brand; 24 October 1929 – 25 December 2012)[1] was an English peer.
Lady Dacre was a daughter of Thomas Brand, 4th Viscount Hampden and 26th Baron Dacre, and his wife, Leila Emily Seely, a granddaughter of Sir Charles Seely, 1st Baronet, and a great-great-granddaughter of John Russell, 6th Duke of Bedford.
She was also a great-granddaughter of William Montagu Douglas Scott, 6th Duke of Buccleuch and through him a direct descendant of Charles II of England.
The ancient English barony, created by writ of summons, fell into abeyance between her and her younger surviving sister (The Hon Mrs Ogilvie Thompson) upon her father's death in 1965 and was called out of abeyance in 1970 in favour of The Hon Mrs Douglas-Home, whilst the Hampden viscountcy passed to her uncle.
They were third cousins, due to their common descent from James Hamilton, 1st Duke of Abercorn.
